Designed with input from Stan's NoTubes' Enduro World Series teams, the new Arch MK3 is ready to own every trail. WideRight optimized for maximum stability with 2.25" to 2.5" tires, we expanded the internal width out to 26mm while keeping the rim incredibly light. A new proprietary alloy and stronger, low-profile rim shape means the new Arch MK3 is built to last. Featuring Bead Socket Technology, the new Arch MK3 also offers the unmatched traction, control, and reliability only found on genuine Stan's NoTubes rims.
